Fred Kasten’s “Talkin’ Jazz” interview with Donald Harrison Jr., originally scheduled for Friday (March 29) at 2 p.m., has been shifted to the same time on Thursday (March 28). The location is the Old U.S. Mint, 400 Esplanade Ave. The event is free and open to the public.

“It’s an opportunity to get a long interview on the record with major figures in New Orleans jazz,” Kasten said. “People who’ve been around awhile and contributed a lot, in my opinion.

“So much of this history is connected. So many of these people have deep roots in the music through their families.

“We try to go back and track where they grew up and how the music played a part in their lives.”

Harrison, who has consulted for and appeared in the HBO drama “Treme,” is a jazz saxophone player and bandleader, as well as a Mardi Gras Indian chief. The series has wrapped production on its fourth and final season, expected to air in the fall.

Kasten, former host of the long-running “Saturday Night Jazz” on WWNO, will return to the station in a regular slot on April 26. “Jazz New Orleans” will air Fridays at 8 p.m.

“It’s sort of New Orleans-centric, but will include not just New Orleans music,” he said. “We’ll feature an interview every week with an artist, combining talk and their music. At some point in each show, there will be a calendar of what jazz can be heard around the city that weekend.”
